The Feedback Eliminator dialog box appears:

Option
Description
Enable Feedback Cancellation
Check the check box to activate the Feedback Eliminator on this
processor channel.
Filter Bandwidth
Bandwidth is determined by the specified Q factor. A lower Q
creates a filter that works across a wider frequency range. A higher
Q utilizes a narrower range.
Filter Depth Mode
Locked: Filters are re-used. A replacement filter, with new settings
and increased filter depth is applied in place of an existing filter.
Unlocked: Adds a new filter at a specific frequency. No filters are
replaced, so this setting will count against the total number of
filters available.
Mode
Choose Voice or Music, depending on the type of audio most
frequently used on this channel.
Note: Voice Mode is the more aggressive setting.

Option
Description
Enable Ringing Elimination
Allows the feedback eliminator to suppress ringing.
Note: This setting adjusts slowly to eliminate ringing.
Run Setup
Click to scan the audio channel for feedback loops and
automatically create notch filters based on your choice of feedback
cancellation settings.
Note: Before you run the setup, you must select the
microphones and gating groups that will be affected.
State
Shows the automatic setup status. Off if automatic setup has not
been run. Running if the automatic setup is underway. Complete if
the automatic setup has been run and is complete.
Number of Fixed Filters
Up to 16 Fixed Filters are applied. If the specified number of filters
are not required, they become Dynamic Filters.
Target Gain Before Feedback
Set your desired dB rating. The unit slowly increases dB, adding
notch filters at detected feedback frequencies until it either reaches
the target level or reaches the number of Fixed Filters (see Number
of Fixed Filters above).
The system detects feedback through an open mic while levels are
increased. If the target is reached without using the specified
number of fixed filters, the remaining “slots” are used as Dynamic
Filters to be applied as the environment changes.
Affected Microphones
Specify the microphone channels to which FBE will be applied.
Note: You must make this selection prior to running the
setup by clicking Run Setup.
Affected Gating Groups
Select the gating groups to which FBE will be applied.
Note: You must make this selection prior to running the
setup by clicking Run Setup.
Reset Feedback Eliminator
Clears all feedback cancellation settings.
Reset Dynamic Nodes
Clears all dynamic filters. Fixed filters remain in place.
Status
Shows how many fixed and dynamic filter nodes are being used.
Feedback Node Report
Creates a text report listing existing filter node details.
Note: If you are not connected to a device or stack, not all the options appear.
